Archimedes’ Principle Lab Mark Wojoski – 249736331 Eric Dewit – PHYS 211 Monday 12:20 27 March 2006 Abstract: In this lab we determined the densities of irregularly shaped objects using Archimedes’ Principle. The masses of three different objects were measured while hanging on a string from a triple beam balance. The masses were measured both hanging in the air and hanging in the water. Archimedes’ Principle was used to calculate the densities of these objects. The calculated density of the cube was compared with the actual density of the cube using the definition of mass density (mass/volume). The results were 2750 kg/m^3 compared to 2998 kg/m^3, which gave us a percent difference of 8.76%.

Introduction: Archimedes’ Principle states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. Archimedes’ Principle is used to explain why big ships and vessels stay afloat in the ocean. In determining whether a given body will float in a given fluid, both mass and volume (density) must be considered. In this
